BACKGROUND OF THE INVENTION

The field of the invention relates generally to a container, and more particularly to a container that includes lines of perforation for removal of a portion of the container for displaying articles for sale.

It is a known practice to employ containers to store and transport sales articles from the manufacturer to the place of sale, such as a retail store. Typically, containers are formed from at least one blank made of corrugated paperboard which is suitably cut, scored and folded to produce a generally rectangular shaped box. Once the carton reaches the place of sale, the articles are unpackaged from the carton and are typically placed on display shelves. One drawback of such containers is that a significant amount of labor is required to remove the articles from the container and, in turn, place them on the display shelves.

It is known that some containers can be utilized to ship the sales articles and are convertible into a display device at the place of sale, thereby eliminating the labor required in transferring the articles from the container to the shelves of the place of sale. Such containers normally include a separable upper section which is torn away from the lower section by a tear strip or perforated tear line formed through panels of the container to expose the packaged articles for display. However, these containers that are convertible to display devices typically have sides and bottom lips on the front of the display devices that make it difficult to see the entire front of the article for sale.

Accordingly, it is desirable to provide a container that is convertible to a display and that includes small bottom corners on the front of the display that facilitates the sales articles from falling out of the display and that permits customers to see the front of the sales articles.

BRIEF DESCRIPTION OF THE INVENTION

In one aspect, a blank of sheet material for forming a container is provided. The blank includes a front end panel, a first side panel, a second side panel, and a back end panel connected in series by a plurality of side fold lines. A front bottom panel extends at least partially from a bottom edge of the front end panel. An opening lip extends from the front end panel across the front bottom edge. The opening lip has a free edge and two opposite ends. The free edge of the opening lip is adjacent to the bottom front panel. Each end of the opening lip is a distance from the side fold lines of the front end panel. A first separation line extends from a first end of the opposite ends of the opening lip toward the first side panel. A second separation line extends from a second end of the opposite ends of the opening lip toward the second side panel.

In another aspect, a shipping container convertible to a display container, formed from the just-described blank, is also provided.

In yet another aspect, a shipping container convertible to a display container is provided. The shipping container includes a front end wall, a first side wall, a second side wall, a top wall, a bottom wall, and a back end wall. An opening lip extends from the front end wall across a front bottom region of the front end wall. The opening lip has a free edge and two opposite ends. The free edge of the opening lip is adjacent to a front region of the bottom wall. Each end of the opening lip is a distance from side regions of the front end panel. A first separation line extends from a first end of the opposite ends of the opening lip toward the first side wall; and a second separation line extends from a second end of the opposite ends of the opening lip toward the second side wall.

In still yet another aspect, a method for forming a shipping container convertible to a display container is provided. The shipping container is formed from a blank having a front end panel, a first side panel, a second side panel, and a back end panel connected in series by a plurality of fold lines. The back end panel extends from one of the first and second side panels. Top and bottom panels extend from opposite edges of each of the front end panel, first side panel, second side panel, and back end panel, respectively. An opening lip extends from the front end panel. The opening lip has two opposite ends. First and second separation lines extend from the opposite ends of the opening lip to opposing ones of the first side panel, the second side panel, the front top end panel and the front bottom end panel. Third and fourth separation lines extend from the first and second separation lines, respectively, through one pair of the first and second side panels, and the front top end panel and the front bottom end panel, respectively. At least a fifth separation line is disposed in one of the first side panel, the second side panel and the back end panel.

The method includes first rotating the back end panel toward an interior surface of one of the first and second side panels, rotating the one of the first and second side panels toward the front end panel, rotating the front end panel toward the other of the first and second side panels. The method further includes rotating a glue flap, extending from one of the rear end panel and the other of the first and second side panels toward the other of the rear end panel and the other of the first and second side panels and affixing the glue flap thereto, forming a rectangular tube. The method further includes rotating the first and second bottom side panels toward the interior of the rectangular tube, then rotating the front bottom end panel and the back bottom end panel, toward the interior of the tube, and affixing the front bottom end panel and the back bottom end panel in place. The method further includes rotating the first and second top side panels toward the interior of the rectangular tube, followed by the front top end panel and the back bottom end panel, which are likewise affixed in place. Opening of the container so formed is accomplished by grasping the opening lip and pulling, causing an upper portion of the container to separate from a lower portion of the container along the lines of separation.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description illustrates the disclosure by way of example and not by way of limitation. The description clearly enables one skilled in the art to make and use the disclosure, describes several embodiments, adaptations, variations, alternative, and use of the disclosure, including what is presently believed to be the best mode of carrying out the disclosure.

A container that includes lines of perforation for removal of a portion of the container for displaying articles for sale, and a blank used for forming the container is described below in detail. The container is constructed from a blank of sheet material using a machine and/or by hand. For example, the blank can be wrapped about a mandrel to form the container or formed using a tray former machine. Alternatively, a folder/glue machine can be used to convey the blank through folder arms and an adhesive applicator to form a knocked-down flat container which can then be fully formed by hand. In another embodiment, the container can be formed by a machine as a wraparound container wherein the container is wrapped around a load of products contained within the container. In one embodiment, the container is fabricated from a paperboard material. The container, however, may be fabricated using any suitable material, and therefore is not limited to a specific type of material. In alternative embodiments, the container is fabricated using cardboard, fiberboard, paperboard, foamboard, corrugated paper, and/or any suitable material known to those skilled in the art and guided by the teachings herein provided.

In an exemplary embodiment, the container includes opposing side walls, a front end wall, a back end wall, a top wall, and a bottom wall. An opening assembly including a lip and access gap is included at the bottom of the front wall. The opening lip extends below the front bottom wall and creates an opening to permit a user to remove the upper portion of the container. In another embodiment, the opening lip extends to a point substantially even with the bottom wall. Perforation lines extend diagonally from each end of the lip. Each perforation line extends to a side wall. Each side wall includes a perforation line extending from one of the front wall perforation lines to the upper corner of the sidewall adjacent the back end wall. The perforation lines form separation regions that enable an upper portion of the container to be removed from the bottom portion of the container, which bottom portion serves as a display container for the articles contained therewithin. Access holes may be located in each side wall adjacent to the side wall perforation line. Another perforation line may extend the width of the back end wall and intersect each of the perforation lines of the side walls.

The container can be converted to a display by a user pulling on the opening lip of the bottom of the front wall to break the perforations of the diagonal perforation lines on the front end wall. The user is able to access the lip by inserting fingers within the access gap for pulling on the lip. Next, the user grasps the two side access holes and pulls outwardly to break the perforation lines on each side. Then the user breaks the line of perforations along the back of the container by pulling from either side to remove the top portion (removable portion) of the container.

Different embodiments described here can vary in size and/or dimensions although similar labels are used for each embodiment. For example, although a depth is labeled similarly throughout the description, each embodiment can have varying depths. In addition, each embodiment includes an opening assembly that is similar to the opening assembly described above.

Referring now to the drawings, and more specifically to FIGS. 1 and 2, although as described above a container may have any suitable size, shape, and/or configuration, FIGS. 1 and 2 illustrate the construction or formation of one exemplary embodiment of a container. Specifically, FIG. 1 is a top plan view of an exemplary blank 100 of sheet material. FIG. 2 is a top perspective view of a container 200 formed from blank 100.

Referring to FIG. 1, blank 100 has a first or interior surface 102 and an opposing second or exterior surface 104. Further, blank 100 defines a leading edge 106 and an opposing trailing edge 108. In one embodiment, blank 100 includes, from trailing edge 108 to leading edge 106, a glue flap 118, a first side panel 116, a front end panel 112, a second side panel 114, and a back end panel 110, coupled together along preformed, generally parallel, fold lines 126, 120, 122, and 124, respectively. More specifically, first side panel 116 extends from front end panel 112 along fold line 120, second side panel 114 extends from front end panel 112 along fold line 122, back end panel 110 extends from second side panel 114 along fold line 124, and glue flap 118 extends from first side panel 116 along fold line 126. Fold lines 120, 122, 124, and/or 126, as well as other fold lines and/or hinge lines described herein, may include any suitable line of weakening and/or line of separation known to those skilled in the art and guided by the teachings herein provided.

First side panel 116 includes a first top side panel 160 and a first bottom side panel 162 extending therefrom along respective fold lines 164 and 166. More specifically, first top side panel 160 extends from first side panel 116 along fold line 164, and first bottom side panel 162 extends from first side panel 116 along fold line 166. Similarly, second side panel 114 includes a second top side panel 140 and a second bottom side panel 142 extending therefrom along respective fold lines 144 and 146. More specifically, second top side panel 140 extends from second side panel 114 along fold line 144, and second bottom side panel 142 extends from second side panel 114 along fold line 146.

Front end panel 112 includes a front top end panel 150 and a front bottom end panel 152 extending therefrom along respective fold lines 154, 156 and 158. More specifically, front top end panel 150 extends from front end panel 112 along fold line 154, and front bottom end panel 152 extends from front end panel 112 along fold lines 156 and 158. Similarly, back end panel 110 includes a back top end panel 130 and a back bottom end panel 132 extending therefrom along respective fold lines 134 and 136. More specifically, back top end panel 130 extends from back end panel 110 along fold line 134, and back bottom end panel 132 extends from back end panel 110 along fold line 136. Fold line 134 includes a perforation/cut line 138.

An opening assembly 169 includes a lip 170 extending from the bottom of front end panel 112 between fold lines 156 and 158, and an access gap 171. Cut line 172 defines opening lip 170. In the embodiment of FIGS. 1 and 2 (as with each of the embodiments shown and described herein), cut line 172 (or its equivalent in the other embodiments herein) preferably extends into the adjacent panel at least the thickness of the blank, or more, so that opening lip 170 extends beyond the bottom wall 210 of container 200 (FIG. 2) when erected from blank 100. In addition to enabling opening lip 170 to extend beyond the bottom of the erected container, the length of opening lip provides for the creation of a gap, between the opening lip and the leading edge of the bottom wall, for the insertion of fingers to facilitate grasping and lifting of opening lip (and, in turn, the upper portion of the erected container). Even if opening lip only extends to exactly the outer surface of the bottom wall of the erected container, a gap for finger insertion is still created. In embodiments (such as the embodiment of FIGS. 15 and 16) where there is a cut out positioned in the bottom wall (or other wall) immediately adjacent to the opening lip, the opening lip may or may not extend into the front bottom end panel.

A perforation line 174 extends diagonally from fold line 156 to fold line 122. Fold line 156 includes a portion 176 that includes a perforation/cut line 178. Portion 176 of fold line 156 extends from opening lip 170 to perforation line 174. Similarly, a perforation line 180 extends diagonally from fold line 158 to fold line 120. Fold line 158 includes a portion 182 that includes a perforation/cut line 184. Portion 182 of fold line 158 extends from opening lip 170 to perforation line 180.

First side panel 116 includes a perforation line 186 that extends from the intersection of perforation line 180 and fold line 120 to the junction of fold line 164 and fold line 126. In another embodiment, perforation line 186 extends from the intersection of perforation line 180 and fold line 120 to another location along trailing edge 108. Perforation line 186 includes a cut out 188 that defines an access opening 190 in first side panel 116. Cut out 188 is positioned on the upper side of perforation line 186.

Similarly, second side panel 114 includes a perforation line 192 that extends from the intersection of perforation line 174 and fold line 122 to the junction of fold line 144 and fold line 124. In other embodiment, perforation line 192 extends from the intersection of perforation line 174 and fold line 122 to another location along fold line 124. Perforation line 192 includes a cut out 194 that defines an access opening 196 in second side panel 114. Cut out 194 is positioned on the upper side of perforation line 192.

In addition, the exemplary embodiment may include a cut-out, score lines, or perforation lines on front bottom end panel 152 to facilitate a user to insert fingers within access gap 171 for pulling on opening lip 170.

Referring to FIG. 2, to construct container 200 from blank 100, back end panel 110 is rotated about fold line 124 toward interior surface 102 of second side panel 114, second side panel 114 is rotated about fold line 122 toward interior surface 102 of front end panel 112, front end panel 112 is rotated about fold line 120 toward interior surface 102 of first side panel 116, and glue flap 118 is rotated about fold line 126 toward interior surface 102 of back end panel 110. In the exemplary embodiment, after rotating panels 110, 112, 114, and 116 and glue flap 118 about fold lines 124, 122, 120, and 126, side panels 116 and 114 are substantially parallel to each other and substantially perpendicular to end panels 110 and 116. Panels 110, 112, 114, and 116 and glue flap 118 can be rotated about fold lines 124, 122, 120, and 126 by wrapping blank 100 about a mandrel within a machine or by using a tray folder machine. Alternatively, a folder/glue machine can be used to convey blank 100 through folder arms and an adhesive applicator to form a knocked-down flat container.

Once panels 110, 112, 114, and 116 and glue flap 118 are rotated about fold lines 124, 122, 120, and 126, glue flap 118 is coupled to back end panel 110. For example, in the exemplary embodiment, interior surface 102 of glue flap 118 is adhered to exterior surface 104 of back end panel 110. Alternatively, exterior surface 104 of glue flap 118 is adhered to interior surface 102 of back end panel 110. Further, although adhesive is described herein, glue flap 118 can be coupled to back end panel 110 using any suitable fastener and/or technique. Once glue flap 118 is coupled to back end panel 110, back end panel 110 and glue flap 118 form a back end wall 202, second side panel 114 forms a second side wall 204, front end panel 112 forms a front wall 206, and first side panel 116 forms first side wall 208 of container 200. From this configuration, partially formed container 200 can be collapsed into a knocked-down flat configuration for shipping and/or storage of container 200.

To continue construction of container 200, first bottom side panel 162 is rotated about fold line 166 toward interior surface 102 of first side panel 116, and second bottom side panel 142 is rotated about fold line 146 toward interior surface 102 of second side panel 114. In the exemplary embodiment, first bottom side panel 162 is substantially perpendicular to first side wall 208, and second bottom side panel 142 is substantially perpendicular to second side wall 204. Front bottom end panel 152 is rotated about fold lines 156 and 158 toward interior surface 102 of front end panel 112, and back bottom end panel 132 is rotated about fold line 136 toward interior surface 102 of back end panel 110. As such, bottom side panels 162 and 142 and bottom end panels 152 and 132 form a bottom wall 210 of container 200, as shown in FIG. 2.

To close container 200, front top end panel 150 is rotated about fold line 154 toward interior surface 102 of front end panel 112, and back top end panel 130 is rotated about fold line 134 toward interior surface 102 of back end panel 110. More specifically, after rotation, front top end panel 150 is substantially perpendicular to front end panel 112 and back top end panel 130 is substantially perpendicular to back end panel 110. First top side panel 160 is rotated about fold line 164 toward interior surface 102 of first side panel 116, and second top side panel 140 is rotated about fold line 144 toward interior surface 102 of second side panel 114. More specifically, after rotation, first top side panel 160 is substantially perpendicular to first side panel 116 and second top side panel 140 is substantially perpendicular to second side panel 114. In the exemplary embodiment, top side panels 160 and 140 overlap when top side panels 160 and 140 are substantially parallel to bottom wall 210. Alternatively, top side panels 160 and 140 are sized such that top side panels 160 and 140 do not overlap when top side panels 160 and 140 are substantially parallel to bottom wall 210. In the exemplary embodiment, top side panels 160 and 140 rest on top end panels 150 and 130 while at least top side panels 160 and 140 are secured together using, for example, tape. As such, interior surface 102 of top side panels 160 and/or 140 is adjacent to and/or in direct contact with exterior surface 104 of top end panels 150 and 130. Top side panels 160 and 140 and top end panels 150 and 130 define top wall 212 of container 200.

Once container 200 has been erected, filled and sealed, upon arrival at its destination, container 200 may be opened as follows: an operator grasps front wall 206 by placing their hand under lip 170 and pulling upwardly. Preferably, perforation lines 186, 180, 184, 178, 174, 192 and 138 are created in such a manner that all will yield in a simultaneous manner, so that upon a continuous upward pulling motion, the operator separates and removes an upper portion 220 of container 200 from a lower portion 222 of container 200.

Similarly, second side panel 314 includes a second top side panel 340 and a second bottom side panel 342 extending therefrom along respective fold lines 344 and 346. More specifically, second top side panel 340 extends from second side panel 314 along fold line 344, and second bottom side panel 342 extends from second side panel 314 along fold line 346.

Front end panel 312 includes a front top end panel 350 and a front bottom end panel 352 extending therefrom along respective fold lines 354, 356 and 358. More specifically, front top end panel 350 extends from front end panel 312 along fold line 354, and front bottom end panel 352 extends from front end panel 312 along fold lines 356 and 358. Similarly, back end panel 310 includes a back top end panel 330 and a back bottom end panel 332 extending therefrom along respective fold lines 334 and 336. More specifically, back top end panel 330 extends from back end panel 310 along fold line 334, and back bottom end panel 332 extends from back end panel 310 along fold line 336. Fold line 334 includes a perforation/cut line 338.

An opening assembly 369 includes a lip 370 extending from the bottom of front end panel 312 between fold lines 356 and 358, and access gap 371 created by opening lip 370. As discussed with respect to the embodiment of FIGS. 1 and 2, opening lip 370 preferably extends into front bottom end panel a length equal or greater to the thickness of blank 300, so as to extend beyond the bottom of the erected container.

Perforation line 372 enables opening lip 370 to be pushed in or removed entirely to permit an operator to reach opening lip 370. A perforation line 374 extends diagonally from fold line 356 to fold line 322. Fold line 356 includes a portion 376 that includes a perforation/cut line 378. Portion 376 of fold line 356 extends from opening lip 370 to perforation line 374. Similarly, a perforation line 380 extends diagonally from fold line 358 to fold line 320.

In the exemplary embodiment, after rotating panels 310, 312, 314, and 316 and glue flap 318 about fold lines 324, 322, 320, and 326, side panels 316 and 314 are substantially parallel to each other and substantially perpendicular to end panels 310 and 316. Panels 310, 312, 314, and 316 and glue flap 318 can be rotated about fold lines 324, 322, 320, and 326 by wrapping blank 300 about a mandrel within a machine or by using a tray folder machine. Alternatively, a folder/glue machine can be used to convey blank 300 through folder arms and an adhesive applicator to form a knocked-down flat container.

Once panels 310, 312, 314, and 316 and glue flap 318 are rotated about fold lines 324, 322, 320, and 326, glue flap 318 is coupled to back end panel 310. For example, in the exemplary embodiment, interior surface 302 of glue flap 318 is adhered to exterior surface 304 of back end panel 310. Alternatively, exterior surface 304 of glue flap 318 is adhered to interior surface 302 of back end panel 310. Further, although adhesive is described herein, glue flap 318 can be coupled to back end panel 310 using any suitable fastener and/or technique. Once glue flap 318 is coupled to back end panel 310, back end panel 310 and glue flap 318 form a back end wall 402, second side panel 314 forms a second side wall 404, front end panel 312 forms a front wall 406, and first side panel 360 forms first side wall 408 of container 400. From this configuration, partially formed container 400 can be collapsed into a knocked-down flat configuration for shipping and/or storage of container 400.

First top side panel 360 is rotated about fold line 364 toward interior surface 302 of first side panel 316, and second top side panel 340 is rotated about fold line 344 toward interior surface 302 of second side panel 314. More specifically, after rotation, first top side panel 360 is substantially perpendicular to first side panel 316 and second top side panel 340 is substantially perpendicular to second side panel 314. In the exemplary embodiment, top side panels 360 and 340 overlap when top side panels 360 and 340 are substantially parallel to bottom wall 410. Alternatively, top side panels 360 and 340 are sized such that top side panels 360 and 340 do not overlap when top side panels 360 and 340 are substantially parallel to bottom wall 410. In the exemplary embodiment, top side panels 360 and 340 rest on top end panels 350 and 330 while at least top side panels 360 and 340 are secured together using, for example, tape. As such, interior surface 302 of top side panels 360 and/or 340 is adjacent to and/or in direct contact with exterior surface 304 of top end panels 350 and 330. Top side panels 360 and 340 and top end panels 350 and 330 define top wall 412 of container 400.

Once container 400 has been erected, filled and sealed, upon arrival at its destination, container 400 may be opened as follows: an operator grasps front wall 406 by placing their hand under lip 370, pushing up opening lip 371, gripping upper portion 420 of container 400 and pulling upwardly against lip 370. Preferably, perforation lines 386, 380, 384, 378, 374, 392 and 338 are created in such a manner that all will yield in a simultaneous manner, so that upon a continuous upward pulling motion, the operator separates and removes upper portion 420 of container 400 from a lower portion 422 of container 400.
